1 Claim.

This invention relates to a mechanical gas generator or gasifier particularly adapted for use with internal combustion engines.

An object of the present invention is the provision of a device for generating a dry gas from liquids capable of being vaporized.

Another object is the provision of a dry explosive gas from liquids, such as crude oil or other liquids of an explosive nature.

Another object is the provision of a gas generator in which the liquid supplied thereto is broken up'into its finest molecular state.

Another object is the provision of a device for generating-gas from liquid fuels which will result in a saving of the liquid fuels along with a decrease in heat loss and carbonization.

A further object is the provision of a device for generating gas from liquids of an explosive nature, in which the gas is completely generated before it is mixed with the proper quantity of air to make it a violent explosive mixture, thereby reducing the possibility of an explosion in the device.

The main purpose of this invention is to obtain the maximum efficiency from the liquid fuel used in connection with internal combustion engines, together with a high margin of safety by reducing the possibility of premature firing or exploding in the gas generator. The fuel is vaporized and broken up into its very finest state by means of air, centrifugal force, friction, and heat, all in a very limited space, and then it is mixed with the proper quantity of air to make it a highly explosive mixture, this last step, how-, ever, being done only immediately before the gas enters the engine.

The present invention consists essentially of a gas generator for internal combustion engines comprising a vaporizing chamber communicating with'the intake manifold of the engine, a drum rotatably mounted in the chamber, corrugations formed on the outer surface of the drum and the inner surface of the chamber, means for rotating the drum, means for supplying liquid fuel to the chamber, means for supplying air under pressure to the fuel before it enters the chamber at least to partially vaporize said fuel, and means for heating the fuel as it passes through the chamber, said fuel being further vaporized and broken up in the vaporizing chamber, as more clearly described in the following specification and illustrated in the accompanying drawings, in which Figure 1 is a front elevation of the generator with the vaporizing drum and cover removed,

part of the front wall and heating plate bein broken away,

Figure 2 is a vertical section through the generator taken on the line 2--2 of Figure 1, with the vaporizing drum and cover in place,

An intake pipe [5 having a, control valve "5 therein, communicates with the interior of the housing It at the bottom thereof while diametrically opposite said pipe, a discharge pipe I! communicates at one end with the interior of the housing, the opposite end of the discharge pipe being provided with a flange l3 for connection with the intake manifold of an internal combustion engine (not shown) The discharge pipe I! is formed with a restriction or Venturi passage adjacent its lower end and with a throttle valve 2| above said restriction or passage.

A ring or circular partition 22 mounted in the housing I0, is spaced from and concentric with the peripheral wall 23 thereof, to form passages -24 and 25 extending from the intake pipe I5 to the discharge pipe IT. A hollow jet or nozzle 26 formed on the ring 22 and communicating with the space bounded thereby, projects into the discharge pipe I! and is adapted to discharge -into said pipe at the Venturi passage 20. A plurality of spirally disposed partitions 21 are mounted in the housing land form a plurality of spiral passages 28, said passages extending from their entrances 30 outwardly in a spiral and terminating at their outlets 3| adjacent to but Within the ring 22.

A sleeve 32 is formed on the wall l2 of the housing and extends inwardly from the opening 14. A hollow drive shaft 33 is journalled in the sleeve 32 and extends beyond each end thereof, said sleeve being provided with suitable bearings 34. A pulley 35 is mounted on one end of the shaft 33 and a conical vaporizing drum 36 is mounted on the other end of the shaft, the

"base of said drum projecting into the opening [3 of the front wall I I of the housing.

The drum 36 is provided with a hub 31 carried by the shaft 33, forming a chamber 38 within the drum, in which an electrical heating coil 40 is mounted. Leads 41 extend outwardly from the coil 46 through the shaft 33 to a suitable source of electrical supply, suitable means (not shown) being provided for permitting the coil to rotate without entangling the leads. A plurality of fan blades 42 extend outwardly from the base of the drum 36 approximately to the rear wall I2 of the housing, said blades overlapping the entrances 30 of the spiral passages 28. A spiral band 43 is formed on the outer surface of the drum 36 and extends from the tip rearwardly to the base of said drum. This band forms a spiral groove 44' The band 43 is rela; tively narrow at the tip of the drum and grad-"- ually widens as it progresses towands the base between its convolutions.

thereof. Similarly, the various convolutions of the band are closer togetherat the tip of the ;f-* drum and gradually get farther apart towards the opposite end thereof so that the groove 144 gradually widens towards the drum base. j

A hollow, conical cover 45 fits over but is spacedfrom the vaporizing drum 36. This cover consists'o-f an inner and outer walls 46 and 41 form- 55 "and 56 areremovably secured, both plates being spacedfrom the housing. A spiral band .51, similar to the band 43, is formed-on .the'inner surface of the inner wall 46 of the .cover 45, said band forming a groove 58fbetween' its convolution's. The band 5'! is arranged so that it overlaps and may even project into'the groove 44 of the drum 36 and, consequently, the band 43 of said drum overlaps or mayj'project into the groove 58 of the cover. Actually, these bands andgrooves (Jo-operate to formtwo spiral passages 60 between the vaporizing drum and the cover. 3

The cover 45 forms a conical vaporizing chamber inflwhich .theconical drum 36 rotates. The outer surface of .the drum is situated quite close to the' inner surface of the vaporizing chamber while b'oth'surfaces are corrugated, the corrugations being formed'by' the bands 43 and 51, This vaporizing chamber communicates with the intakemanifold of the engine through the housing Ill.

lAnozzl'e 6| is formed adjacent the outer end of the vcover 45, said nozzle having a passage 62 communicating with the interior of the cover. A pipeline 63 is connected to the outer end of the nozzle. and extends to a fuel tank (not shown). Ifdesired, a suitable pumping device may be employed with the line 63 for supplying fuel to the nozzle under pressure. An air jet 64 formed iri .the' nozzle is adapted to project air under pressure into the passage 62, said air being supplied .to the jet through a pipe line 65 which is connected to a suitable source. able means'may be employed for varying the pressure and quantity of air supplied to the nozzle; in accordance, with the'speed of the engine with whichthis device is used.

. 'A suitable governor 66 is mounted on the drive shaft 33 between the housing II] and the outer end of .said shaft." This'governor consists of a collar: 61mou'rited upon'and rigidly secured to If desired, suit- I site ends, to the collars 6! and 68, each spring f collar 61. cured to the rear wall l2, may be employed to 1 9.556.?11? governor having a weight 13 mounted thereon substantially midway between the ends thereof; and a spiral spring 74 mounted on the shaft 33 and extending from the flanged end of the sleeve '16 to the If desired, a cover 15 removably seoperation, air under pressure and liquid fuel are'supplied to the nozzle 6| through pipes 65 and 63 respectively. The fuel'is partially vaporized in-the nozzle and then discharged on to the tip of the rotating drum 36. The fuel is either blown' or drawn through the chamber formed between the drum and the cover 45, depending upon the speed of the engine on which. the der, vice is mounted. The fuelisvaporized inthis chamber by heat from the coils 40 and 56 in the drum and cover, respectively. The spiral groove 1 44 assists the movement of the vaporized fuel towards the opening I3'of the housing [I]. At the same .time',.the vaporizedfuel is subjected to centrifugal force and friction as it passes over the surface of the rotating drum as it is thrown outwardly-by the drum and strikes the unevenor corrugated-surface of the inner wall of-the cover. The fan blades 42' direct the vaporized fuel or gas into andthrough the spiral passages 28. In these passages, the fuel is further broken up by centrifugal force and friction. If desired,'additional heat may be applied to the fuel in the spiral passages'byany suitable means in the spaces. between the, covers 55 and 56 and. the housing/ l6, 's'uchas, forexample, by means of exhaust gases from the engine, which may be directed.

through. said spaces; .The gas is then directed. by the ring 22 to the nozzle 26, through which it is drawn. or blown into the Venturi passage 20 where it is mixed with a suitable quantity of air .to make it a violently explosive mixture for firingv in. the engine. This last-mentioned air enters the housing [0 through the intake pipe l5 and passes along the passages24 and 25 to the Venturi passage. This air is at least slightly l' preheated by the gasesinside th ring 22 and by theheating means inside the plates 55 and 56, if said heating means is employed. j The partially. vaporized fuel expands'when it enters'the chamber between the vaporizing drum and'the cover. This increases the 'pressure in 1 theichamber but the corrugated drum and inner wall of the cover prevent the'gases from passing. too'rapidly out of'the chamber. When the gases' enter the housing II!) from the vaporizingchamlf berfthe fan .blades'42- direct thegases into the}:

spiral passages j 28'a'nd, 'at the same time, assist;

thatonly such limitations shall be placed there on as are disclosed in the prior art or are set forth in the accompanying claim.

Having now described my invention and the nature of same, what I claim and desire to be protected in, by Letters Patent, is:

A gas generator for internal combustion engines comprising a circular housing having a discharge pipe adapted to communicate with the intake manifold of the engine, an air inlet in the housing spaced from the discharge pipe, an air passage in the housing communicating with the air inlet and the discharge pipe, a conical vaporizing chamber communicating at its base with the interior of the housing centrally thereof, a conical drum rotatably mounted in the chamber, corrugations formed on the outer surface of the drum and in the inner surface of the chamber,

means for rotating the drum, a plurality of spiral storage passages in the housing extending outwardly from the central portion thereof, means for supplying fuel to the chamber at the tip thereof, means for supplying air under pressure to the fuel before it enters the chamber at least partially ,to vaporize the fuel, said partially vaporized fuel being directed on to the tip of the drum, a heating element in the drum, a heating element in the wall of the vaporizing chamber, means at the rear of the drum for directing fuel from the vaporizing chamber through the spiral passages, and means for mixing the vaporized fuel from the spiral passages with warm air from the air passage before entering the intake manifold of the engine.
